Bosch 0986259207 exhaust gas temperature (egt) sensor for the 2013-2015 Audi Q7 V6 3.0L reads exhaust heat and sends it to the ECU. That data helps protect the turbo, catalytic converter, DPF and SCR system from thermal overload.
- Stainless steel housing, ceramic insulator and glass-to-metal hermetic seals for exhaust streams above 1,600°F
- Temperature data helps the ECU time regeneration events and optimize dosing
- Monitors DOC/DPF inlet and outlet temperatures to confirm the regeneration window and complete soot burn-off
- Tracks SCR inlet temperature so dosing happens in the proper thermal window, helping prevent urea deposits on injectors and mixers
- Connects to the ECU software over CAN-bus for onboard diagnostics
Quick facts
- Part: Bosch 0986259207 exhaust gas temperature (egt) sensor
- Fits: 2013-2015 Audi Q7 V6 3.0L
- Position: Before SCR catalyst
- Condition: New
A warning light, or regeneration cycles that are missed or incomplete and raise backpressure and fuel consumption, can mean the sensor is not reading correctly. Before you replace it, rule out damaged wiring, a loose connector and a fault in the DPF or SCR system, since a problem in any of them can also light the warning.
Fits
This sensor fits the 2013-2015 Audi Q7 V6 3.0L and mounts ahead of the SCR catalyst.

Frequently Asked Questions
Does the Bosch 0986259207 EGT sensor fit the 2013-2015 Audi Q7 V6 3.0L?
Yes. Bosch 0986259207 is listed for the 2013-2015 Audi Q7 V6 3.0L, and the vehicle takes one sensor.
What is the housing of this Bosch EGT sensor made of?
The housing is stainless steel, with a ceramic insulator and glass-to-metal hermetic seals. The sensor is built for exhaust streams above 1,600°F.
Where does the Bosch 0986259207 sensor sit in the exhaust?
This sensor sits before the SCR catalyst. There it tracks SCR inlet temperature so urea dosing happens in the proper thermal window.
What can a failing exhaust gas temperature sensor look like?
Possible signs are a warning light or missed or incomplete regeneration, which raises backpressure and fuel consumption. A shop can scan the system and test the sensor.
Does 4H0906088F cross to this Bosch EGT sensor?
Yes. 4H0906088F is listed as an interchange number for Bosch 0986259207.
